What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMyelofibrosis (MF) is often characterized by a multifactorial anemia determined, in part, by bone marrow (BM) fibrosis, extramedullary erythropoiesis and splenomegaly. Ruxolitinib (RUX) is the first-in-class janus kinase 2 (JAK2) inhibitor approved for treatment of MF, proved to reduce spleen volume and decrease symptom burden. The red cell distribution width (RDW) is the measure of erythrocyte volume variability (anisocytosis). RDW has been recognized as a marker of clinical and subclinical systemic inflammation, and its elevation has also been associated with poor outcome in a wide spectrum of benign disorders and in different types of neoplasms.
methodsWe retrospectively evaluated RDW in a single-center series of 200 consecutive patients with primary and secondary MF at RUX treatment initiation and examined any possible correlation with adverse MF features or drug-related anemia and any prognostic impact.
resultsWe suggested 20.5% as the optimal cutoff point in RDW values at start of RUX to dichotomize patients in receiver operating characteristic (ROC) analysis for spleen response and for survival. Higher RDW values at RUX start were associated with clinical and laboratory features of an aggressive MF phenotype. Lower spleen response (p < 0.001) and greater odds of drug-related anemia at 3 (p = 0.006) and 6 months (p < 0.001) were also seen in patients with higher RDW. Both increased RDW (considered as a continuous variable) and RDW ≥ 20.5% were associated with shorter overall survival (OS) from RUX initiation in univariate and multivariate analysis: HR 1.25 (95% confidence interval [CI], 1.12-1.40) (p < 0.001) and HR 3.01 (95% CI 1.81-4.99) (p < 0.001), respectively. RDW ≥ 20.5% at RUX start seems to possibly improve patients' sub-stratification along with anemia and conventional prognostic scoring systems.
conclusionsRDW at RUX start might represent a good indirect measure of MF features and might have prognostic significance for RUX-treated patients affected by MF, aiding in the rapid detection of patients with poor prognosis.
